Hi I work in a lab doing QA tests on concrete cubes and cylinders, we are looking into prism block testing should I use ASTM C39 as my pint of reference? And are there any recent changes I should consider?

Answer
Yes, the method given in the ASTM C39 "Standard Test method for Comressive Strength of Cylindrical Concrete Specimens" can be used for testing concrete specimens of prismatic shape. If the requirement is of compressive strength only, there are no extra precautions to be taken, other than those required normally for cylindrical specimens.
